No, I don't think the "Big 10" or "Heavy Half" was available for 4x4 trucks.
According to the info kits from
http://gmheritagecenter.com/gm-herit...tion-kits.html, the RPO F44 "Big 10" is only listed for C10 2 wheel drive trucks. And according to the GVWR selector tables in those kits, the GVWR on all 1976 through 1980 K10 (1/2 ton 4x4) trucks is 6200 lbs.
As was mentioned earlier, the whole idea of the Big 10 was to bump the GVWR up above the 6000 lbs. threshold. That allowed buyers to purchase a 1/2 ton truck that didn't require catalytic converters & other emissions equipment that was required on lighter trucks. But since the 1/2 ton 4x4 trucks were already above that threshold, there wasn't any need to raise the GVWR any higher.
